Two weeks ago, I had the privilege of visiting our two new offices in China in conjunction with all-day launch events for COMSOL Multiphysics version 4.4. Both events were greatly successful; Shanghai attracted a hundred or so attendees, while Beijing received almost one hundred and fifty.

Each year, electrical and electronic engineers and designers share their groundbreaking work in the IEEE Spectrum® insert, Multiphysics Simulation. In this 2014 edition, top tech companies and research institutions, from around the globe, share their simulation stories. We are excited to announce that you can now read and download the magazine on our website!

There are two main resources for finding COMSOL Multiphysics tutorial models: our online Model Gallery and the Model Library within the software. We also continuously push out model updates that you can download to your Model Library. Here’s your guide to what these resources are and how to use them.

One thing we haven’t talked much about so far in the Hybrid Modeling blog series is what speedup we can expect when adding more resources to our computations. Today, we consider some theoretical investigations that explain the limitations in parallel computing. We will also show you how to use the COMSOL software’s Batch Sweeps option, which is a built-in, embarrassingly parallel functionality for improving performance when you reach these limits.

In the latest post in this Hybrid Modeling blog series, we discussed the basic principles behind shared memory computing — what it is, why we use it, and how the COMSOL software uses it in its computations. Today, we are going to discuss the other building block of hybrid parallel computing: distributed memory computing.

Mixers with rotating components are essential in many industrial applications, including food production, manufacturing chemicals, pharmaceuticals, and other consumer products. While the industrial processes of mixers differ, product requirements like quality, reproducibility, and uniformity must remain constant. Using the Mixer Module is one way you can make sure these product requirements are met. In our upcoming webinar, you’ll learn how the fluid flow interfaces available in the Mixer Module allow you to streamline the design of mixers and their mechanisms.

It’s no news that accurate mechanical analysis is key to avoiding product failure and manufacturing issues. What may be new is how you do it. Simulation software offers a modern approach to analyzing mechanical component and system designs. Watch this video to learn how COMSOL Multiphysics enables you to speed up time-to-market and optimize product designs.

One of the questions we get asked all the time is: “Can I use COMSOL Multiphysics for solving my fluid-structure interactions problems?” Of course the answer is yes, so let’s talk a little about the various fluid-structure interaction (FSI) modeling techniques. Along the way, we will introduce the add-on modules you will need for these various types of analyses.

Previously in this blog series, my colleague Pär described parallel numerical simulations with COMSOL Multiphysics on shared and distributed memory platforms. Today, we discuss the combination of these two methods: hybrid computing. I will try to shed some light onto the various aspects of hybrid computing and modeling, and show how COMSOL Multiphysics can use hybrid configurations in order to squeeze out the best performance on parallel platforms.

A couple of weeks ago, we published the first blog post in a Hybrid Modeling series, about hybrid parallel computing and how it helps COMSOL Multiphysics model faster. Today, we are going to briefly discuss one of the building blocks that make up the hybrid version, namely shared memory computing. Before that, we need to consider what it means that an “application is running in parallel”. You will also learn when and how to use shared memory with COMSOL.

Twenty years ago, the TOP500 list was dominated by vector processing supercomputers equipped with up to a thousand processing units. Later on, these machines were replaced by clusters for massively parallel computing, which soon dominated the list, and gave rise to distributed computing. The first clusters used dedicated single-core processors per compute node, but soon, additional processors were placed on the node requiring the sharing of memory. The capabilities of these shared-memory parallel machines heralded a sea change towards multicore […]
